Oregon entered Saturday’s game against Stanford averaging a national-best 54.8 points per game.

It left with 14 and a loss that at the very least has severely damaged its national championship hopes. Stanford upset the Ducks, 17-14, in overtime. Jordan Williamson nailed a 37-yard field goal to clinch the victory and topple the Ducks’ season.

Stanford brought its bruising running back, Stepfan Taylor, and its bone-crushing linebackers to Autzen Stadium and gave the Ducks the kind of fight they aren’t accustomed to.

In the end, Stanford was the team left standing.

Zach Ertz got control of Kevin Hogan’s pass just before falling out of the back of the end zone to tie the game 14-14 after the extra point with 1:35 left.

With the game tied, 7-7, De’Anthony Thomas’ 6-yard slippery touchdown run with 6:35 left in the third quarter looked like it would hold up. The Ducks started the drive at their own 5-yard line and marched down the field to set up Thomas’ go-ahead score.

On the ensuing possession, Stanford fumbled and Oregon recovered. While the Ducks didn’t score, they did take time off the clock, and with a game this close, minutes and seconds meant everything.

Not until the fourth quarter, after 10 plays, did Stanford tie it up.

The game went into overtime and that’s something the Ducks, who have creamed everyone, had not experienced all year. It was something Stanford, on the other hand, was all too familiar with.

Stanford had already come close previously to disrupting the BCS picture in overtime. On a controversial play, it was stalled on a goal-line stand against Notre Dame in the extra period.

The Cardinal were determined not to go down that way again.

In overtime, Oregon got a chance first to go up. Alejandro Maldonado, however, missed a 41-yard field goal.

Stanford fumbled on its ensuing possession, but recovered. That gave Williamson the chance to lift his team to one of the biggest upsets of the season.
